Description

Heat exchange element of window ventilation device and heat exchange module comprising same {HEAT EXCHANGE ELEMENT OF VENTILATION EQUIPMENT FOR WINDOW AND HEAT EXCHANGE MODULE COMPRISING THE SAME}

The present invention relates to a heat exchange element of the ventilation device for windows and doors, and more particularly, is installed in the window frame to discharge the air of the indoor space to the outdoor space and to introduce the air of the outdoor space into the indoor space Heat exchanger element used in heat exchange module of ventilation device for windows and doors that enables inter-exchange heat exchanger. Heat exchanger and sensible heat exchanger with both heat exchanger and sensible heat exchange. It is about.

In general, the content of carbon dioxide contained in the air of the indoor space is gradually increased over time by the breathing of life. In addition, since the increased content of carbon dioxide interferes with the breathing of life, the air in the indoor space should be replaced with fresh air in the outdoor space from time to time.

In general, the air in the indoor space is forcibly discharged to the outdoor space by a ventilation device such as a blower, and the air in the outdoor space naturally flows into the indoor space through the opening of a window. However, if the air in the indoor space is replaced in this way, the total heat exchange between the air in the indoor space and the air in the outdoor space is not made, so unnecessary cost is required for heating or cooling the indoor space. Due to the rapid temperature change of the problem occurs that can cause people to feel uncomfortable. Here, the total heat exchange is a concept including both sensible heat exchange, meaning temperature exchange, and latent heat exchange, meaning humidity exchange.

Generally, a heat exchange element is an apparatus for obtaining a fluid of a desired temperature by providing a heat exchange member to cross a high temperature fluid and a low temperature fluid. The heat exchange element is manufactured and used in various forms, and a plate-type heat exchange element that increases an area where heat is exchanged by stacking a heat exchange plate made of a thin plate of a predetermined area is mainly used.

The heat exchanger plate of a conventional plate heat exchanger is mainly manufactured using aluminum or plain paper. When using a heat exchanger plate made of aluminum, the structure of a body frame for stably and rigidly stacking a metal heat exchanger plate is complicated and the production cost is increased. There is a problem that is increased. In addition, there is a problem that only heat is exchanged and humidity is not exchanged.

In addition, the use of paper heat exchanger plate reduces the production cost compared to aluminum. The paper also transmits humidity and exchanges both heat and humidity. However, in the process of use, the paper heat exchanger plate is weak in strength due to its weak strength. There is a problem that must be replaced from time to time by being easily damaged by.

The present invention enables the heat exchange between the air discharged from the indoor space to the outdoor space and the air introduced from the outdoor space to the indoor space, and at the same time, the excellent strength and heat / humidity exchange capability of the aluminum and paper heat exchanger plates.
